ABSTRACT:
Method and apparatus for aiding hearing are disclosed comprising an automatic gain control unit which includes a first section for increasing the amplitude of input signal segments that are below a threshold level, and a second section for reducing the amplitude of input signal segments that are above said threshold level. Both sections have short attack and long release time constants. A long attack short release time constant noise suppressor unit responsive to the output from the second section and having a threshold level of operation below that of the threshold level of the automatic gain control units passes speech signals and squelches background noise signals between speech signal segments for improved understandability of speech signals.
